APPARATUS FOR WINDING SILK, 86C.

SPECIFICATION forming part of Letters Patent No. 495,479, dated April18, 1893. Application filed July 21,1892. Serial No. 440,831. (Nomodel.) Patented in France April 25, 1891, No. 221,156.

To a/ZZ whom t may concern.-

Be it known that I, EDOUARD FoUGEIRoL, a citizen of the Republic ofFrance, residing at Paris, France, have invented certain new and usefulImprovements in Apparatus for Winding Silk and other Textiles, of whichthe following is a specification.

This invention is the subject of Letters Patent in France, dated April25, 1891, No. 221,156.

In the winding of silk from the skein to the bobbins as now practiced,the skein is carried on a very light octagonal frame called a silk reel,which is rotated by the unwinding `of the filament from it as it iswound on to the bobbin or spool. However light this silk reel may be,its weight, with that of the skein it carries, is sufficient to impose aconsiderable strain upon the filament, which is extremely attenuated, sothat it is difficult to drive the reel. at a speed exceeding fortyrevolutions per minute. Efforts have been made to increase this speed bytransmitting to the reel a differential speed, with means forautomatically stopping it in case of breaking the filament, but up tothe present these efforts have not been practically successful. I haveinvented a system by means of which the speed of the windin g may beconsiderably increased without adding appreciably to the tension of thefilament. By my system I keep the silk reel and the skein station ary,and draw off the filament by unwinding it rotatively from the skein.

Let us suppose the silk reel mounted horizontally on the ground,with apolished metal ring or cap of semicircular section laid over it so as tooverhang or inclose and embrace all the extremities of the eight arms ofthe reel. Then by drawing the thread from the skein, carrying it overthis ring, and passing it through a glass eye in the axis of the reel,the thread may be drawn off without other resistance to overcome thanthat of its own weight, its adhesion to the other filaments of theskein, and its friction against the polished surface of the metal cap,the radius of which is only two or three centimeters greater than thatof the skein. The unwinding thread will describe a co'ne the apex ofwhich is formed by the glass eye, and the base by the annular cap. Bythis arrangement the reeling may be effected at any desired speed,because the friction of the thread over the cap or ring isinsignificant. The large amount of room required for the reelingoperation would however be a serious objection. This difficulty,however, is overcome by arranging the reelin its usual vertical positionand placing the glass eye quite near the reel, only seven or eightcentimeters from the plane of the annular cap or ring, whereby the spaceoccupied is scarcely greater than that of a common silk reel. The threadthen during the reeling will describe a very flat cone. This arrangementwill considerably increase the friction of the thread over the ring,which might cause breakage. To reduce this friction, I provide forrotating the annular cap or ring at the same speed as the rotatorymotion of the filament in reeling off.

Figure l of the accompanying drawings is an elevation illustrating theordinaryprocess of reeling off. Fig. 2 is a sectional elevation on alarger scale illustrating the application of my invention. Fig. 3 is ahorizontal section through thereel and its accessories.

In the ordinary construction shown in Fig. l, the skein T is carried onthe reel TX, and the filament is drawn therefrom over suitable guidesand Wound on the bobbin B", turning in the direction of the arrow, andthereby imparting rotation to the reel in the direction of the arrow T2.

Referring to Figs. 2 and 3, let B designate the Winding-on bobbin, T thereel, and d the filament or thread being drawn from the reel to thebobbin. The hub M of the reel is placed over a tubular stationaryspindle b formed as a projection on a bracket E, which is fastened by aset-screw P on the usual vertical supporting rod A (shown in section inFig. 3). The reel Will remain stationary on this hollow spindle, but maybe turned by hand in order to search for the end of the filament.Through the hollow spindle b passes a rotatory spindle f carrying fastand loose pulleys p and p at one end, and having fastened at the otherend the hub-carrying arms O supporting the ring or annular cap F. Thisring F is preferably made of sheet metal semi-circular in cross-sectionso as to be hollow, and of a diameter very slightly larger than that ofthe reel, in order that it may be IOO applied close against the side ofthe reel and in a plane parallel thereto and preferably concentrictherewith (although a slight degree of eccentricity might not beinjurious). The filament is drawn from the skein, carried over the ringF, and passed through a glass eye c at the center or axis of the reel,from which it is carried up to the winding-on bobbin B. The ring F isrevolved at a speed proportionate to the speed of the bobbin B and fromthe same source of power through the medium of a spindle e carrying apulley over which passes a cord or belt g running over the fast or loosepulleys p or p.

The purpose of rotating-the ring F is to reduce the friction of thefilament in passing over it. With a stationary ring the filament movesover the ring obliquely, its motion resolving itself essentially intotwo movements, one in a radial direction across the face of the ring,and the other in a rotative direction traversing the ringcircumferentially. The former motion is attended by a very insignificantfriction, while the friction of the latter movement is much greater andis accompanied by much greater liability of the filament being torn bycontact with minute and imperceptible roughnesses on the ring. Thisrotatory movement of the filament relatively to the ring is overcome bymovement of the ring at approximately the same speed as that which thefilament assumes as it reels off. It results from this that the filamenthas little or no movement against the ring otherwise than that oftraversing it transversely, by which its contact with the ring is verybrief, and is accompanied by the minimum of friction.

The advantages resulting from my improved mode of reeling off are veryimportant, because not only may the speed be at least quadrupled, butthe silk reel being stationary, the iilament, which has only its ownmass to carry away, will when broken cease to move and can beimmediately found and tied, while by the old method the torn filamentwas carried away by the reel, which continued its motion on account ofthe momentum due to its acquired speed. It will furthermore be possibleto purge or clear the thread by my invention during the reeling, whichhitherto has necessitated a second operation.

My invention is not confined in its application to the winding of silk,but may be applied with other textile fibers.

I claim as my invention the following-defined novel features,substantially as hereinbefore specified, namely:

1. The improved apparatus for winding silk or other textiles comprisingin combination with a reel on which the skein is wound, a rotativelymounted hollow ring of greater diameter arranged in a planeapproximately parallel therewith and adjacent thereto, and overhangingthe reel, having a smooth rounded outer surface over which the iilamentis drawn and by which it is carried outward and laterally free from thereel, and a central eye through which the filament passes and from whichit goes to the winding-on bobbin.

2. The combination with the reel on which the skein is wound, of astationary mounting therefor, a ring arranged adjacent thereto overwhich the filament is drawn, a central eye through which the filamentpasses to the winding-on bobbin, and means for revolving said ring at aspeed approximately equal to the speed of unwinding of the lament,whereby the filament is carried around by the ring, but is not drivenpositively.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses. v
